Zusammenfassung: | PURPOSE: A manufacturing method of charged particles of an electrophoresis display device is provided to obtain 'charged particles which has a great electrophoresis mobility' by controlling charge amount of charged particles through the number of peak periods of a main chain and a side chain and a quantity of charge control agent and including an ultraviolet ray blocking layer in white charged particles. CONSTITUTION: White/black pigment particles are formed(st1). The surface of the white pigment particles is reformed by an ultraviolet ray blocking layer. Colloid solution is formed as 'a polymer resin which includes a main chain and a side chain' and the white/black pigment are firstly dispersed into a solvent(st2). A charge control agent is secondly dispersed into the colloid solution(st3). Charged particles are separated and refined from the solvent(st4). [Reference numerals] (AA) Form white pigment particles; (BB) Reform the surface of the white pigment particles; (CC) Form black pigment particles; (st2) Form colloid solution that binder and color pigment(black pigment particles or white pigment particles) are firstly dispersed into a solvent; (st3) Secondly disperse charge control agent into the colloid solution; (st4) Separate and refine the charged particles from the solvent |
